00:00:00.000 --> 00:00:05.758
Here is the problem: Find the slope and equation of the line through (2, 7) and (8, 7).

2
00:00:06.208 --> 00:00:09.888
Find the slope (rate of change) of the line through two points.

3
00:00:10.688 --> 00:00:11.837
Label the points.

4
00:00:12.287 --> 00:00:14.214
Find the change in y (rise).

5
00:00:14.664 --> 00:00:16.347
Find the change in x (run).

6
00:00:16.797 --> 00:00:18.329
Divide rise by run.

7
00:00:19.130 --> 00:00:22.207
Find the y-intercept using the first point.

8
00:00:22.657 --> 00:00:24.282
Write the equation of the line.

9
00:00:25.082 --> 00:00:29.157
So the answer is m equals 0; y equals 7.

10
00:00:29.607 --> 00:00:36.225
The slope is 0: for every 1 unit increase in x, y changes by 0. The line is horizontal.

11
00:00:37.025 --> 00:00:42.377
Second point: 0 times (8) plus 7 equals 7 (expected 7).
